Cannot import ASGI_APPLICATION module while runserver using channels 2
In my case it was wrong import in different file.
What you should do is
python manage.py shellfrom mysite.routing import applicationLook what exact error it produces and try to fix that
Just change
ASGI_APPLICATION = mysite.routing.application
to
ASGI_APPLICATION = "routing.application"
Check for any potential errors (maybe import error) in consumers.py. Also, try to put channels as the first item in INSTALLED_APPS in settings.py.
As stated in channels document:
The Channels development server will conflict with any other third-party apps that require an overloaded or replacement runserver command. An example of such a conflict is with whitenoise.runserver_nostatic from whitenoise. In order to solve such issues, try moving channels to the top of your INSTALLED_APPS or remove the offending app altogether.
